How this service works
Use to vet a developer, owner, architecture firm or trade contractor in the Rio Grande Valley, Texas: projects filed since late 2024 (count, total and largest cost, cities, dates, newest projects) and state trade licenses held by the business (A/C, electrical, sign, elevator), current or expired. Pass part of the name (3+ characters). No match is a free 404. Example: "How many projects has this developer filed in the Valley since 2024, and how large was the biggest one?"
Output
Returns a JSON object listing matched companies (up to 10 names) with their role (owner or design firm), cities and counties of activity, state trade licenses, first and last seen dates, project count, latest project details (address, scope, type of work, estimated cost, status), and aggregate cost figures. Also includes dataset metadata such as coverage counties, data freshness, cadence, and disclaimer.
Example use cases
School district construction activity research
“Search Frontera Signal for 'independent school district' and show me which ISDs have filed construction projects in Hidalgo or Cameron County, with their total estimated costs and most recent project details.”
Vetting a design firm before bidding
“Look up 'Sam Garcia Architects' in the Frontera Signal companies data — I want to see how many projects they've been involved with, which counties they work in, and what their largest project cost was.”
Monitoring a developer's pipeline
“Can you check Frontera Signal for any companies matching 'Anzalduas' and tell me their project count, project costs, and when they were last seen filing construction work in South Texas?”

Endpoint
GEThttps://fronterasignal.com/api/v1/companies?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to identify or profile construction companies—owners or design firms—active in South Texas border counties (Hidalgo, Cameron, Starr, Willacy), especially when researching project history, license status, cost estimates, or geographic footprint by partial company name. It is particularly valuable for competitive intelligence, due diligence on contractors, or tracking school district and municipal construction activity in the Rio Grande Valley.
Side effects
- Missing required 'name' query parameter returns a validation error
- Name too short or too generic may return up to 10 matched company names with truncated results
- No matching companies returns an empty companies array
- Stale data (over 14 days since weekly update) is flagged in the disclaimer field
- Payment failure (x402) returns a 402 response requiring USDC micropayment
